Smart Programmable Ultraviolet Germicidal Irradiation System

Case ID:

This invention is a sanitizer that utilizes UV radiation to sanitize closed rooms. The invention will be able to be programmed and automated to precisely deliver the exact does of UV radiation around the area of interest while also considering safety. The sanitizer will irradiate UV light with multiple beam steering devices to selectively sterilize the different areas in a room. 

The appearance of SARS-CoV-2 in 2019, created a pandemic that resulted in 775,431,269 infections, and a total of 7,047,741 deaths worldwide as of May 2024. The pandemic also led to a large demand for deployable sanitization solutions to eliminate, reduce, and control the viral transmission of the virus. Current UV sanitization solutions tend to be non-programmable, static, and fixed. UV sterilizers that are already on the market that utilize UV lightning as a germicide tend to be imprecise, as their UV radiation system only tend to illuminate different areas indiscriminately and non-uniformly.

Given the current UV lightning sanitization solutions that are currently on the market, there is a high need for a new technology that is both portable and automatic. A new technology that could solve the imprecision, uniformity, and mobility problems could improve the rates of sanitization in work environments, schools, and markets, where a high number of occupants is present in a single room.
